TABULATO FDR TYPEWRTERS.

Application filed December 24, 1921. Serial No. 524,643..`

ing a speciiication. v v V This invention relates to a tabulator tortypewriters and consists oi: a system ot,`

levers by means ot whicl'rthe carriage may be released and permitted tomove ilreely7 the carriage being afterwards stopped atk anypredetermined point.

fin embodiment olf the invention is illustrated on the aocompanying`drawing.

l is a perspective view oft the lator arranged on the carriage bed.

Fig. 2 is a plan View of part ofthe atinginechanism-` Fig. 3 is a detailview oil' part oit Fig. `2 on an enlarged scale.

Fig. et is a cross section ot the carriage bed and the operating andstopping mecha* nism on a line il. A ot Fig. 3.

Fig. 5 is a cross section olf the carriage bed and the operating' andstopping mechanism on a line B-B ot llifg. 3.

l is the carriage bed plate above which are arranged a rack 2 andreleasingn lever 3 having' two pivotal points et about which it isadapted to rock, and also having upright end portions or handlessaidflever 8 being' kept in its place by means of a spring 22. ist oneend ot the carriage bed and below this bed is arranged a key le r 6having a linger piece or cap 7, a pivot point 8 and a short arm 9passing` upwards through a hole in the bed and meetingthe end ole onearm l of a sub-lever pi'voted at its center, as indicated at il. uponthe bed plate l. The opposite arm l2 ot the sub-- lever is provided withan uptiiirned terminal lap or hook 13 which meets the lever fit theunderside ot' thebed plate l is ranged a movable stop gill which isslidably mounted by means ot two screws i6 moving in a groove l in thestop i-l, theflatt having a pair ot' struck-up lugs l'Tp-assinp; upthrough an opening i8 in the bed plat l and embracing` the lever armll2.

At the back of the carriage iframe and connected thereto is a bar 19carrying one or more slidable tabulator stops 20, Qi which are fastenedby means ot screws :23.

When the tabulating` mechanism is to be tabu- `forward beneath the bedl.

`lever tor directly operating' said with the carriage;

used7 the ley lever 6 is pressed downward, the arm 9 thereby pressingagainst the arm l() oilw the sidi-lever,` so that the .latter is*yrocked and its hool` 13, in turn, rocks the. lever E andV simultaneouslydisengages the usual pawl mechanism (notshown) from the rack "4 therebyreleasing the carriage. At the sameitime the arm l2 presses against oneot the lugsll and moves the stop 14 The carriage now .lovesautomatically until the stop la meets the first stop 20, Awhere it stopsand remains for the period wanted, the spring `22 moving the lever 3,the arml 12 `andthe stop 14 back into their original positions."

A second depression otthe ltey lever 6 will again release thecarriageand m'ovethe stop 14 `forward to engage thenext station- 'f ary stop 2letc.

In view of its plain andsimple construe-A` tion and slight weight theinvention is spef*y cially applicable to" portable typewriters,

but also in many cases be used with advantage by stationary typewriters.

Having now particularly described and ascertained the nature ot my saidinvention l declare that what l claim is:

l. ln a typewriter, the combination with a carriage bed over which acarriage is adapted to travel, letten'teed mechanismy and carriagerelease mechanisni; of a taloraA latino; key lever mounted on saidcarriage bed; a sub-lever pivotally mounted on said bed and operateddirectly by said tabulatu ing; key lever; means `carried by said subcarriage release mechanism; stops mounted to move and a stop slidablymounted on said carriage bed and movable directly by said sub-lever intothe path ot travel. ot the carriage stops and eoncomitantiy with releaseot the carriage. 2. ln a portable typewriter, the combination with acarriage bed plate over which a carriage is adapted to travel,letter-feed methanism and ca riage release mechanism; of a tabulatingrkey lever mounted on the carriage bed plate; a sub-lever mounted topivot on a vertical axis on said bed plate and operated directly by saidkey lever and vadapted to operate said carriage release sub-lever"vmovesy the movable, stop to and from stopping position.

3. In a portable typewriter, the combination with a carriage bed overwhich a carriage is adapted to travel, letter-feed mechanism andcarriage release mechanism; of a tabulating key-lever mounted on thecarriage bed; stops mountedtomove with said carriage; and a sheet-metalstop mounted onsaidca'rriage bed to move transversely thereacross and ina horizontalplane and having aI struck-up lug engaged directly and bysaid sub-lever by means of Which the sub-lever moves the movable stop tostopping position.

4. In al typewriter, the combination, with a carriage bed over Which acarriage is adapted to travel and escapeinent mechanism for thecarriage, of--carriage release mechanism including a releasinglever forthe escapement mechanism; a tabulating key lever; a sub-lever pivotallymounted ,on thefcarriage bedcand operated directly by said key lever,the sub-lever having a` part engageable With the releasing,` lever toactuate the same; stop mounted yto move With the carriage; and a stop.slidably mounted on the carriage ,bed and movable directly by thesub-levernivith the path of the carriage stops and concomitantly Withthe actuation ofthe releasing lever. y

5. In atypevvriter, the combination of a carriage bed plate over which acarriage is adapted to travel; a tabulating key lever pivotallyconnected thereto; a sub-lever pivoted on said bed plate in position tobe operated by the tabulating lrey lever; carriage-release mechanismincluding a releasing lever directly operated by the sub-lever; stopsconnected to niove with the carriage; and a movable stop carriage by thebed plate to be shifted by the sub-lever into and outof position forcoaction with the firstnamed stops.

6. In a typewriter, the combination of a carriage bed plate over which acarriage is adapted to travel, said plate having` a slot adjacent oneend; a tabulating key-lever pivotally mounted below the bed plate andhaving a hook which .projects upwardly through said slot; a sub-leverpivoted on said plate to move in a horizontal plane and having one enddisposed in the path of said hook to be actuated thereby; car-`riage-release mechanism inclrding;V a releasing lever positioned to bedirectly engaged and operated by the sub-lever; stops con-r nected tomove With the carriage; and a movable stop carried by the bed plate tobe shifted by the sub-lever into and out of position for coaction withthe firstnamed stops.

In testimony whereof I atliX my signature.

JACOB srIM MARoUssEN.
